The Electro-Harmonix Ravish Sitar Synthesizer Guitar Effects Pedal has a polyphonic lead voice and tunable sympathetic string drones that react to your playing. Decay time for the lead voice is adjustable, and custom scales can be assigned to the sympathetic strings. Pitch bending and volume adjustment are made easy with two expression pedal inputs. Complete tonal flexibility is easy to achieve when you are able to create a totally unique and organic instrument.
